STOP'AND WASTE COCK. i

SPECIFICATION forming' part of Letters Patent No. 66i',737, dated February 12, 1901.

Application iiled June 7, 1900.

To all wwm/ t hefty concern:

Be it known that I, VILLIAM H. RAWE, a citizen of the United States of America, residing at No. 92 North Main street, in the city of Pawtucket, county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Stop and Waste Cocks, of which the following is a specification.

My invention relates to stop and waste cocks which have to be arranged in various positions and of that class having a wasteport adjustably combined with the valve and case, so that the discharge of waste water may be applied in any direction.

My invention consists in the combination with a valve-case inclosing a water-passage and having a partition dividing said waterpassage, said partition havingacircularopening, a valve-seat surrounding said opening, a circular flanged hub integral with the valvecase and having an interior circular iange, the axis of which is in alineinent with the axis of the valve-seat, said hub screw-threaded upon its interior surface, a cylindrical sleeve-nut mounted in the screw-threaded opening ot' the said huh and having a centrally projecting portion provided with a screw-threaded opening to receive the thread of the valve-stein, said sleeve-nut having an exterior screw-thread at the extremity of its projecting portion, a series of longitudinal openings through the said sleeve-nut at prescribed distances around the projecting portion of the same, a swiveled cap surrounding the projecting portion of said sleeve-nut and inclosing the said series of openings, said cap having a waste-tube integral therewith, and a collar surrounding the valve-stem and screwthreaded upon its interior surface to engage the threaded end of the projecting portion of said sleeve-nut, with packing rings interposed between the aforesaid parts, as hereinafter described and claimed.

Referring to the drawings, Figure l represents a sectional view of the waste-cock, showing the valve closed and the waste open. Fig. 2 is a similar view showing the valve open and the waste closed. Fig. 3 is a central sectional view of the sleeve-nut. Fig. 4

is a cross-sectional view of the sleeve-nut,

serial No. 19,443. (No model.)

taken in line c 0c of Fig. 3. Fig. 5 is a perspective view of the packing-ring for the sleeve-nut. Fig. 6 is a front elevation of the swiveled cap and its waste-tube. Fig. 7 is a cross-sectional view of the waste-cock, taken in line y y of Fig. l. Fig. 8 is an elevation of the waste-cock on a reduced scale.

Similar letters refer to similar parts in the different iigures of the drawings.

A denotes the shell or valve-case, having a water way or passage divided by a partition b into two parts c and d, respectively. The partition h is provided with a circular opening e, forming a communication between the parts c and d of the water-passage. .valve-seat surrounding the opening e, against which the circular valve-disk g rests in closing the said opening. This valve-case has a circular iianged hub a integral therewith and provided with an interior screw-threaded surface, said huh having an interior annular ange 72, provided with a circular opening t, the axis of which is in alinement with the axis of the valve-seat.

p is a packing-ring which is made to rest against the flange h and is provided with a circular opening of a lesser diameter than the opening of said flange.

B is the valverod, having an enlarged screw-threaded section extending outwardly from the location of the packing-ring p and having an enlarged circular headj integral with its inner end thereof, adapted to tit the opening in the flange h of the hub when the valve is open. (See Fig. 2.)

gis the valve-disk, secured upon the enlargementj of the Valve-rod by a screw Z.

C represents a cylindrical sleeve-nut constructed in the form as illustrated in Figs. 3 and 4, having a circular flanged inner portion m and provided with an exterior screwthreaded surface to engage the screw-thread of the hub a. This sleeve-nut has an enlarged flanged head m with an outer projecling portion m2, provided with a centrallyscrew-threaded opening m3 to' engage with the threaded section of the valve-stem. Said projecting portion of the sleeve-nut is provided with an exterior screw-thread m4. A series of openings o extend through the flanged head m at prescribed distances apart fis an annular IOO from each other to form water-passages comn1 unicating from the inner chamber m5 of the said sleeve-nut.

1J is a packing-ring which is made to fit in a circular groove r, formed in the face of the flanged head m' of the sleeve-nut.

D is a cap of a hemispherical form, having a centrally circular opening s, adapted to be mounted upon the projecting portion m2 of the sleeve-nut and with its largest end face resting against the packing-ring p', as shown in Figs. l and 2, and is designed to form a chamber inclosing the water-passages o of the sleeve-nut, said cap having a waste-tube t integral therewith and communicating with the chamber thereof.

E indicates` a check-nut having a central circular aperture of a diameter to receive the valve-stem and its circular flange i; screwthreaded on the inside to engage with the screw-threaded end m4 of the sleeve-nut. This check-nut has a circular recess formed upon its inner face, within which is located a packing-ring p2.

The operation of my improved waste-cock is as follows: Assuming the cock to be arranged in a horizontal, vertical, or other p0- sition and with the valve closed, as illustrated in Fig. l, the waste as it passes from the pipe c' will surround the valve-stem beneath the enlarged head j thereof and continue through the water-passages, as indicated in the arrow direction, and passing through the waste-tube t of the cap D, which is revolved to any degree to discharge the water in a place to receive it, and as the check-nut E is screwed up firmly upon the sleeve-n ut it compresses the packing-rings p and p2, preventing leakage and also securing the waste-tube in position. In opening the cock the valve-stem having a coarse pitch of thread will quickly withdraw the enlarged headyl upon the face of the packing-ring'p and close oft the water from the waste-tube, the water passing from the supply-pipe d' to the pipe c', indicated in the arrow direction in Fig. 2. This construction of a stop and waste cock has the advantage of having no spring to weaken and get out of order.

My device being all brass With the exception of the packing-rings is very readily adjusted, as when the packing-rings become worn by tightening the sleeve-nut and checknut, respectively, compresses and spreads the said rings, so as to be as good as new.

Having described my invention, what I claim is- 1. In combination with a valve-case, of a stop and waste cock, having a partition dividing a water-passage, said partition having a circular opening, a circular flanged hub integral with said valve-case and provided with an interior screw-threaded surface, said hub which is in alinement with the axis of the valve-seat, a packing-ring in said hub adjoining said annular fiange, a sleeve-nut having a circular flanged end provided with an exterior screw-thread to engage with the screwthreaded hub of said valve-case, said sleevenut having an enlarged head m with an outwardly-projecting portion m2 provided with an exterior screw-thread m4 at the extremity thereof and a central screw-threaded opening to engage the screw-thread of the valve-stem, a series of longitudinal openings 0 extending through the enlarged head of said sleeve-nut and communicating with the inner circular chamber m5 thereof, said head provided with a central circular groove surrounding said series of openings, with a packing-ring p in said groove, a circular flanged cap D mounted upon the projecting portion ol said sleeve-nut and bearing against the last-af0resaid packing-ring, said cap having a waste-tube integral therewith and communicating with the chamber thereof, with a check-nut E having a central circular aperture ot' a diameter to receive the valve-stem and its circular ilange U screw-threaded on the inside to engage with the screw-threaded end m4 of the sleeve-nut, said nut provided with a circular recess to receive a packing-ring p2, adapted to impinge against the waste-cap D and hold the same in position, as shown and for the purpose specified.

2. In combination with the valve-case A having a circular flanged hub t provided with an interior screw-threaded surface with an interior flange 7L, a packing-ring p in said hub adjoining said annular flange and provided with a central circular opening, the cylindrical sleeve-nut C mounted in the said hub as shown, and having an enlarged head m provided with a series of openings o, and a central screw-threaded opening, a circular groove r in the head of said sleeve-nut and surrounding said series of openings 0, a packing-ring p' in said groove, with the valvestem B mounted in said sleeve-nut and provided With a-n exterior screw-thread to engage with the threaded portion m2 of said sleevenut, said valve-stein having au enlarged circular head integral with the inner end thereof' adapted to hear against the packing-ring p in closing the waste, the cap D mounted upon said sleeve-nntand havinga waste-tube integral therewith, with the check-nut E having a packing-ring p2, said nut adapted to engage upon the sleeve-nut and secure the said cap in any degree of rotation, as shown and described.
